    Surely this is too hot?

    Click link for screenshots of my temperarture of my MacBook Pro Core Duo 2.16ghz 2GB ram. I also have a few screen issues and that darker grey line just above the connection ports on the right has lifted slightly (ill post a pic).

    I think I should complain to apple, do i have valid grounds for a replacement/repair?

    Thanks Graham

    i think its to hot it should be working bettween 30-50 oC

    Though I don't have a MBP, my MB is currently reading 54C and its been running for about an hour with iChat, Firefox, NeoOffice and iTunes open...

    Apple will say it is within spec...

    anything lower than 100 degrees is fine... according to them

    thanks for your numbers, if anyone else could please post there temperatures it would give me a better idea whether its too hot, or just warm...

    these temperatures were taken around 1-2hrs of use using msn, safari, itunes and mail.

    I've pushed my MacBook (2GHz Core 2 Duo) to around 65 running Parallels - figure the W2K VMs I run don't have very good power managment.

    Most of the time though it sits at 40-50 range.

    of curse you've got a faster CPU (more heat), and the Core 2 Duo is supposed to be a little cooler, and there is the 2GB of memory... All adds up. But it does look a little high all the same.

    That's definately too hot. My C2D MBP never exceeds 74 degrees celsius. Perhaps the core duo models run 10 degrees hotter, but IMO that's too hot.

    Charging and running adium, mail, safari, transmission - 43C.

    MBP Core Duo 2GHz

    Fans come on at about 60C, I've seen it get to 80C when pushing it with Parallels. Currently sitting at 56C/131F just writing this post (with Parallels, iTunes, Entourage & DreamWeaver running - OK, it's probably working with that lot!).

    I use a Griffin iCurve - *really* nice bit of kit, gives the desk back. I've got a fan under that to quietly move the air around to cool the MBP.

    Had one set of fans replaced recently. And the motherboard. And it's going in shortly for the buzzing inverter.

    i've noticed mine goes up to 87°C sometimes with firefox, open office, adium, popbarrier, itunes, iphoto running.

    i think that's the perfect temperature for brewing coffee.

    My MBP usually gets above 80C when doing processor intensive tasks, I find it pretty hot, but Apple will probably say it's within spec.

    It's funny that people haven't been through this issue yet on some MBPs. I guess the issue is still cropping up on refurbs.

    There was a loooooong running problem of really bad application of thermal paste on the chipset, cpu, and gpu. It was causing extremely high temps (especially the case temperature -- burning your legs).

    Apple will probably "fix" it for you. I, and many others, reapplied our thermal paste manually and it fixed the temperature levels to a comfortable level.

    something's up with that. I know at high 60s the fans *should* kick up to near maximum if not the maximum.

    That's hot.

    Even tho I'm on a mac book that is way to hot . I have safari, itunes, word and skype open and I am running at 45 Celcius.

    That does seem very hot. I have a 17" MBP C2D (2.33ghz) and it's normally running about ~50ish Celsius with a couple programs open like Dreamweaver, fireworks, excel etc... When I'm playing WoW it jumps up to I'd say no more than 65C.

    you are fine I would say if you are 70c and under...laptops get warm...they all do...

    Mine has good days and bad days. Sometimes it hovers around 80ºC - 90ºC when idle, and other days (like today), it floats around 54ºC with Safari open.

    CoreDuo 1.83 GHz (demanding a replacement soon, there's so much wrong with it I really don't feel like I've spent anywhere near £1500 on it).

    That's very much within spec.

    The fans don't even hit their full rotational speed until the sensors detect 72 degrees. My MBP often runs at this temp, just make sure not to block the outlets at the rear.

    My MacBook C2D 2.0 GHz is fluctuating between 50º ~ 53º C writing this message with only Camino open.

    I use smcfancontroll and when ever mine gets around anything close to 60 I max out the fans and get it back down.

    highest i ever got it was 72c ish when editing a number of large images in Aperture with other programs running in background

    normally 43-55c

    I've gotten to 80-82 but I have to max the CPU usage (Handbreak encoding h.264 from DVD does the trick).

    Since when is "within spec" a variable idle temperature range of 30 degrees C? That's absolutely ridiculous.

    If you're referring to the "72 degrees" as when your temperature sensor reads 72, it has no bearing whatsoever on when the fans actually kick in. There are multiple heat sensors in the MBP.

    Reapplying thermal paste has the temp transfer working properly to the heat pipe which kicks the fans on much sooner that 72 degrees and keeps your laptop at a nice cool 40-45 degree range.

    With the heatsink being so cool (heatsink A) and the processors so warm. I can only conclude that the guy in the factory did not fully secure down the processor to the heatsink, or put too much/little thermal paste on.

    That used to happen to my old P4 PC before I got my C2D 17" MBP, as I frequently removed the heatsink to swap out with new processors etc. and all that it needed was the heatsink reseating.
